Definitely NOT. That valve requires back pressure from the tub spout being closed to force the water to the sh0wer head, so if you have both going to the SH, the tub spout of course can not ever send water to the top side (shower head side) of the valve. You will gain nothing, but a little more added expense at best. One thing I have 'heard' of people doing, though I am quite sure not legal in many areas of the country, is to remove the water flow restrictor (often a little plastic piece in the shower head just under the screen) to allow a heavier flow. I have heard that people that do do this must also make sure that all pieces of the restrictor are removed or shaken from the shower head to ensure that the water is not still restricted by debris. Sometimes, this would also require a slightly thicker washer if the restrictor is attached to one of the washers, though, I would really not know as I would never try to circumvent the government from trying to legislate how i TAKE MY SHOWER. If not for them I might drive 200mph, never wear a seat belt or helmet and stand on the top rung of a ladder!
